Title: Turbine controller
Inventor: IIJIMA TADAHIKO
IPC: G05B9/02
Filed: 1986-03-24
Abstract: PURPOSE:To always maintain the control stability and to secure the high responsiveness by providing a function to ensure a continuous operation even in case all operations are not completed within a fixed cycle while attaining a fixed arithmetic cycle. CONSTITUTION:If a timer is actuated to show the start of the next cycle during execution of an arithmetic program 6, the program 6 is discontinued. However an arithmetic end deciding circuit 5 decides an under-operation mode and indicates the continuation of operation (restarting place) to the head of an arithmetic command circuit since an end flag is not set at '1'. Then a cycle arithmetic selection circuit 2 cancels the final end instruction of an arithmetic command circuit 3 and adds an indication for the element to be calculated in the relevant cycle. Thus the program 6 restarts the operation at a point where the operation is temporarily stopped and skips an idle arithmetic program 7.

Title: Double twisting apparatus
Inventor: KAWASAKI NOBUAKI
IPC: D01H7/86
Filed: 1980-05-15
Abstract: PURPOSE: A double twisting apparatus designed to reduce the diameter of the ballooning part of a yarn automatically with the decrease in the diameter of a cheese according to the advance of the yarn unwinding from the cheese, and achieve the energy saving.  
     CONSTITUTION: A yarn is drawn from a snail wire 4 via a ballooning part (a 2 ) while unwinding the yarn from a cheese (A) to carry out the twisting operation. In the process, the snail wire 4 is lowered gradually with the decrease in the diameter of the cheese (A) due to the yarn unwinding therefrom. The diameter of the ballooning part (a 2 ) is automatically reduced by the lowering of the snail wire 4, and the air resistance in the ballooning part (a 2 ) at a high rotational speed can be reduced so much. Thus, the energy can be saved.

Title: Conveyer
Inventor: HAGA TAKESHI
IPC: H01L21/677
Filed: 1987-03-18
Abstract: PURPOSE:To eliminate exchange of rails and adjustment of width of rails in a conveyer for lead frames or the like of conductor devices by providing a feed roller in such a manner as to incline to the conveying direction so as to press an article to be conveyed against a guide of such a rail by a component of the force caused by the inclination. CONSTITUTION:A rail 2 transversely disposed to carry lead frames 1 or the like is provided with a lead frame feed roller 4 disposed at a small inclination thetawith respect thereto. The feed roller 4 inclines in such a manner that the upper portion thereof inclines to the advancing direction, so that, when the lead frame 1 is conveyed, such all inclination produces a component of the force which causes the lead frame 1 to be pressed against a guide 3 provided at the lower portion of the rail 2, permitting accurate feed of the lead frame 1 in the conveying direction A along the guide 3 of the rail 2. Thus, the guide provided only a side of the rail is satisfactorily effective, and change in width of lead frames can be accomodated without exchange of rails and adjustment of width of rails.

Title: Solid state image pickup device
Inventor: KANTANI MASASHI
IPC: H04N5/335
Filed: 1983-04-15
Abstract: PURPOSE:To eliminate the synchronous noises and to avoid a malfunction by supplying a pulse to a shift register circuit of a solid state image pickup device after detecting that no pulse exists at any register stage. CONSTITUTION:A transistor 140H becomes nonconductive when no high level pulse exists at the corresponding stage of a horizontal shift register 116H. A wired OR is obtained between the outputs of these transistor and register by a lead 144H, the lead 144H is set at a high level only when all stages of the register 116H have no high level pulse. Then a monostable multivibrator 200H is driven. If >=2 high level pulses exist incidentally at the register 116H by some reason, the monostable multivibrator 200H is first driven after the final pulse is delivered from the final stage output 118H. Thus just a lapse of a field period is required.

Title: Magnetic wedge for slot of rotating electric machine
IPC: H02K3/493
Filed: 1992-03-24
Abstract: PURPOSE:To provide a magnetic wedge which gives optimum characteristics to various motors at a low price, and which does not lower the withstand voltage characteristic of the motor, and further, which can be inserted automatically into the slot of the motor without damaging the coils of the motor. CONSTITUTION:To the central part of the surface of a non-magnetic thin leaf-like material 4a such as a polyester film and an aramid paper, an amporphous thin band whose length is nearly equal to the dimension of a stator core and whose film thickness is about several micrometers to several tens of micrometers is bonded. Thereby, a cheap magnetic wedge 4 wherein both of the material 4a and the band 4b are stuck fast together is given. The non-magnetic thin leaf-like material 4a and the amorphous thin band 4b are made into a sheet in a body. Therefore, the magnetic wedge 4 can be inserted into the slot of a stator by a conventional automatic inserting machine. Also, the quantity of the coils stored in the slot of the stator of a motor is not reduced by inserting the magnetic wedge 4 into the slot. Further, the coils are prevented from escaping from the wedge to the opening part of the slot, and by virtue of the non- magnetic thin leaf-like material 4a, which is thiner than the amorphous thin band 4b, the band 4b is prevented from peeling or being damaged, when inserting the wedge 4 into the slot automatically.
